An individual who has shoved their head so far up their ass they've found a way to make themselves more of a fagot than emo kids. They can't dress like a half-way descent human being, can't talk without making themselves seem like a self righteous douche bag, can't play more than two chords on a guitar and most certainly cant do art. Doesn't matter who you are, if you think you can deem the title "hipster" you'll find yourself shitting where you eat.

first of all, there are the fake hipsters.
aka- the girls who have summer "hipster" blogs on tumblr. they think being hipster is wearing high-waisted shorts and wearing crosses on their necks. they still listen to nicki minaj and kesha.
no.
that is not a hipster.
a hipster is someone who simply does not give a fuck.
they appreciate what they want to appreciate.
they dress mostly in sweaters and plaid.
and they listen to bands no one has ever heard of before.

"omg lewk at me im a hipstur!!!!!!! trianglez 4 lyfe!!!!"- not a hipster

A Hipster is a neo-beatnik bent on individuality and seeking a culture previously underground or unique. The word Hipster is synonymous with poser. See poser. A hipster will never claim being a hipster unless they are jokingly denouncing hipsterism and are in fact an individual.

"Hipster chicks are hot, I like the way they dress, they listen to good music"
"Yes, but creative women with their own tastes who dress like hipsters, and listen to hipster music out of their own enjoyment are the ones you want to talk to".

Hipsters are a subculture of American consumer for whom the idea behind the marketing holds more value than the product being marketed.

The attachment of certain words, phrases or ideas to a product (e.g.; counter-culture, independent or "indie", progressive, alternative or "alt", organic, holistic, "old-school", etc.) whether that product is music, fashion, technology, food, social media or real estate, is enough to connote to the hipster "authenticity" and value, regardless of whether there is any innate value to be found.

Ironically, the hipster perceives him/herself as the counterpoint to mass-culture and conformity when, in fact the ease with which hipster "culture" can be appropriated, repackaged and marketed makes them the ultimate conformists (e.g.; tattoos were once a sign of rebellion and a badge of one's outsider status, now over 40% of all Americans under 50 have a tattoo, essentially making them all members of the same tribe.)

Definition #1 was clearly written by a hipster.

Gay porn used to feature nothing but hairless meth-addled circuit queens, now we have to watch skinny, bearded hipsters get facials.

Befuddled observer: "It's 79 degrees out, why are you wearing a kitted wool cap?"
Hipster: "Because I reject the mainstream banality of weather in favor of an authentic expression of my inner self."
Befuddled observer: "Oh, I thought it was because you're a hipster douche-bag."
